The most powerful attack in Final Fantasy VII of Squares Final Fantasy series. Omnislash is the character Cloud Strife's final limit break, consisting of 14 repetitive critical slashes followed by a powerful leaping cleave.

Cloud's ultimate Limit Break. Cloud assaults his oppenent with a long series of powerful sword attacks (15 hits). This may be used against a single enemy or a group; either way, this is an extremely powerful attack. With the correct sword in hand, this attack can actually cause just as much, if not more, damage that the fabled "Knights of the Round" Materia.

A writer or work of slashfanfic that contains a multitude of pairings. Often used to refer to writers that will write any pairing, no matter how implausible, simply because it is slash and therefore good.

Derives from omni (all) and slash, the plethora of Final Fantasy 7 yaoi also likely playing a part.
